No problem, I had to take a look at this previously too.

I think you could change that line all together, or you could possible 
add a
new device by editing both if_bfe.c and if_bfereg.h.  Maybe something like:

I've never done this before, but It would be fun to see if this is all you
need to do.  Best of luck.
